Application filed October 29, 1927. Serial No. 229,596.

The invention has relation to lanterns designed for the reception of an electric light socket and bulb, an object being to simplify the manufacture of lantern frames oi square, hexagonal or other polygonal cross section, and to reduce the cost of maiiul'arcture thereof.

The invention comets in the novel construction and combinations of parts and to the process set forth in the appended claims.

in the accompanying drawings, illustrating an embodiment of the invention, Figure l a side view of the complete lantern irame; lligure 2 is a cross section on the line 22, Figure 1; Figure 3 is a side View of the flat toned casting blank before being bent up into form; Ii igure a is a side view of the. opposite side of said casting blank.

in these drawings the numeral 1 designates the lantern frame casting which is of one piece or integral and made of brass or other metal of sufficiently flexible nature to enable the lantern to be readily bent up into form, said casting having upright corner posts 2 of angular cross section and upper and lower transverse connecting bars 3 of straight cross section. The endmost corner posts 2 have sectional connecting bars l designed when the frame is bent into form to be brazed or connected together at 5.

The corner posts 2 are each formed of side members 3 joined along one longitudinal (.(lgtl and of fixed angular relation to each other and are provided with upper and lower glass retainer lugs 6 integral therewith, and with lower glass stop lugs 7 also integral therewith and in line with the lower transverse connecting bars 3, said stop lugs bridging the longitudinal migularly related. side members 3 oil the corner posts and the adja cent portions of the connecting bars 3 to brace the same.

lhe lantern frame is cast as a flattened blank with the transverse connecting bars in arcuate or curved form as shown in Figure l, with the side members 8 oil the corner posts tfcn'ming end extensions of the curve or arc, and in being bent up into form the connecting bars will assume straight form in line with the side members 3 oil the corner posts, owing to their flexibility, as shown in Figure 2, whereas the corner posts 2 being of angular cross section are sulliciently still so as not to be attested by the bending operation and to retain their straight upright character. In

bending the frame into form it only necessary to bring the connecting bars straight and in line with the side members 3 of the related corner posts as s ated to complete the hexagonal or other polygonal form of the frame, after which the sectional connecting bars are brazed or connected together to hold the lantern frame in form.

In a lantern l'rame of hexagonal cross sec tion the corner posts will have the upright angularly related side members 3 thereof intersecting at an'angle of degrees, whereas in the case of a lantern frame of square cross section the upright angular-1y related side men'ibcrs oi? the corner posts will meet at an angle of 90 degrees, etc.

The vertical glass retainer lugs extend inwardly radially of the corner posts in converging relation, and are adapted to retain the glass insert sheets 8 which a re slipped into each panel of the lantern frame from above, the lower horizontal glass stop lugs 7 limiting. the downward movement of the glass plates.

The lantern frame is adapted to be made up in ornan'iental form 01 various designs, not only as to the polygonal cross section of the lanterns, but also as to the ornamental finish of the corner posts and of the connecting bars thereof.

Owing to the fact that the side members 3 oil the corner posts 3 meet at an angle, and that the curved connecting bars have their end portions in line with said side members 3 transversely when the frame is bent up into form to straighten out the side members 3 the bending strain is spread throughout the length oi the connecting bars and not limited to the ends thereof, so that there will be no tendency to break the connecting bars at their juncture with the corner posts.

in the process of making the lantern frame, the one piece flattened blank is first cast in one piece, after which the curved flexible connecting bars are bent into straight form and in line with the adjacent side members 3 of the still'ened corner posts 3 whereupon the frame will' have assumed polygonal form. The predetermined angle at which the side members 3 of the corner posts intersect is determined by the square, hexagonal or other mhygonal cross sectional form of the co1nplete lantern.

The factthat the curved connecting bars 2 are at their ends in line with the side men1- here 3 of the corner posts 3 transversely is an incident of the Way in which the lantern frame is made in the embodimentof the invention disclosed. Essentially the curved connectling bars have their adjacent end portions 3" angularly related to each other and to said corner posts, Which angular relation is not altered When the frame is bent up into form and is predetermined by Whether the lantern frame is to be of square, pentagonal or other cross section, being determined by dividing the number of sides of the polygon into 860 degrees. A further advantage of casting the lantern frame in the form of a flattened blank that the blanks may be shipped and stored in the flat thereby saving much space and expense.

I claim 1. A one piece integral metal frame of polygonalcross section having upright stiff corner posts of angular cross section, each having side members intersecting each other at a predetermined angle and upper and lower flexible connecting bars of straight cross section, said corner posts having radial conv'erg ing glass retainer lugs and horizontal glass stops.

2. 'A one piece integral metal frame of polygonal cross section having upright stiff corner posts of angular cross section and flexible connecting bars of straight cross section and having at their adjacent ends a predetermined angular relation to each other and to said other posts, the latter having radial converging glass retainer lugs and horizontal glass stops.

3. A one piece flattened metal frame blank having upright stiffened corner posts and flexible bent transverse connecting members, whereby the blank may be bent into hollow polygonal form by merely straightening said connecting members.

4. A one piece flattened metal frame blank having upright stiffened corner posts including each side members joined along one longitudinal edge and of fixed angular relation to each other, and flexible bent transverse connecting members of straight cross section.

5. A one piece integral metal frame of bollow polygonal form having upright corner posts including each side members joined along one longitudinal edge and of fixed angular relation to each other and connecting members of straight cross section.

6. A one piece metal frame of hollow polygonal form having upright corner posts including each side members joined along one longitudinal edge and of fixed angular relation to each other and having horizontal glass stops bridging said side members and bracing the same in their angular relation, and connecting members of straight cross section.

In testimony whereof I aflix my signature.
